Novel L.E.D. source for interior lights

I just found a great source for l.e.d. boards to use in interior light fixtures, especially the ones from the '70s. These come from canabalizaing 12V worklights designed to power from lighter/12V accessory sockets. The board is 2 3/4" X 6" and has two ranks of 30 super white l.e.d.s wired separately. The board is easily removed and can be wired for 30 or 60 l.e.d.s at a time. Resistors for 12V operation are already on the board. The boards are a perfect fit in the older reading lights over the beds in '70s models. Just mount one on each side with hot glue or epoxy and they're plenty bright. See pics. The lights sell for @ $10 at various discount stores.

Great idea!
Where did you find them at? A quick search shows $25+. I'd rather the $10 version.

Yes I would also appreciate information on where to get them for #10. Sounds better than making my own from scratch.

This is pretty cool. Any idea on the AMP draw for one of these?

Got a picture of the reading lights? I don't think my '78 Argosy had any. A PO put in some tacky stick up things that of course no longer work and will be a real pain to remove .

Any idea if these boards would work for the light over the stove

Hey, that is CHEAP. By comparison, the 36-LED PCBs from superbrightleds.com are $20. The current draw seems about proportional so I bet the light output per LED is similar. So this'd be about a quarter the price there.

I think that these two boards are the answer to many an A/S lighting problem. The narrow one from the round light will make a great valence light in the front end and area lights in storage compartments etc.. Can't beat the price and the baords are good quality and easy to extract. Good luck.

Here's the l.e.d. array out of the other cheap work light offered by My Discount Tools:

Discount Tools the Online Bargain Tool Source

and others. This is a nice little board with 60 l.e.d.s arranged in 15 rows of four. It is designed to power up as 15 x 2 and 15 x 4. It could be cut down the center to make two narrow strips. I'm using it for valence indirect lighting among other things-they're only $8!

These a good boards for some jobs. However, please keep in mind that the current draw (wattage) IS NOT representative of the light output (lumens). Different LEDs have much different lumens per watt specifications. Although it seems that they should be proportional values, that isn't the case for LEDs.

With that said, these are still good boards for experimenting and learning and the cost is relatively inexpensive.

I support LEDs

I get it Klattu.......so watts different about what I said......I believe I was giving the LED boards a thumbs up.....just cautioning the users not to expect performance based on power consumption. I was being additive, not negative. Overall, I think it is great to see folks using unique approachs to use LEDs.
